  1. Normal usage is defined as: Screen always On, Brightness 50%, WiFi and Bluetooth OffEye tracking and synthetic speech used continuously for 5 minutes every 20 minutes. 
    Idle is defined as: Screen always On, Brightness at lowest setting, WiFi and Bluetooth Off. Device idle.
  2. Track box describes the space in front of the eye tracker where the user must have at least one eye to get gaze data. The eye tracker is at a 20° angle looking upward from below the screen.
  3. The degree-of-accuracy and precision over percentage-of-population numbers result from extensive testing across representatives of the whole population. We have made use of hundreds of thousands of diagnostic images and performed tests on approximately 800 individuals with different conditions, vision, ethnicities, everyday dust, smudges or blemishes around their eyes, with eyes out of focus, etc. This has resulted in a much more robust and high performance eye tracking experience and a much more realistic representation of true performance across the whole population, not just in a mathematically "ideal" scenario.
